<strong>TSUBAKI</strong> <strong>CAM</strong> <strong>CLUTCH</strong><br />

<strong>TSUBAKI</strong> offers the most complete and versatile<br />

selection of one-way clutches in the industry.<br />

Cam Clutches are precision devices which lock the<br />

inner and outer races, through the wedging action of<br />

cams, to transmit torque in one direction of rotation;<br />

and overrun in the opposite direction. These units are<br />

often referred to as freewheels, sprags, overrunning,<br />

backstop or one-way clutches, depending upon their<br />

application.<br />

Design Features<br />

Full Cam Complement<br />

The full complement of cams provide the maximum<br />

number of load transmitting members per given<br />

diameter. The result is a greater torque capacity sizefor-size<br />

than other clutches.<br />

Cam Design<br />

Precision formed cams made of a special alloy steel<br />

provide extra long wear and fatigue life.<br />

High Quality Components<br />

The clutch races are made of high-quality alloy steel<br />

with high surface hardness and core toughness. The<br />

races are precision ground, provide excellent<br />

concentricity and surface finish to obtain accurate<br />

cam rotation.<br />

Taking Advantage of Differences in<br />

Rotating Direction and Speed...<br />

<strong>TSUBAKI</strong> Cam Clutches<br />

One-way clutches are efficient mechanical devices that utilize differences in axial<br />

rotating direction and the speed of rotation to prevent reverse rotation and ensure<br />

safety. In order to create a more reliable uni-directional clutch, engineers have<br />

spent many years developing and improving clutches, from the simple prop type,<br />

to the ratchet type and the roller type, and then culminating to the Cam Clutch,<br />

which has become the mainstream. The <strong>TSUBAKI</strong> Cam Clutch introduced here is<br />

a cam-type, one-way clutch that is the leading clutch of today.<br />

■ STANDARD SPRAG TYPE <strong>CAM</strong> <strong>CLUTCH</strong> CONSTRUCTION<br />

The figure shows a representative model from the MZ Series for explaining construction.<br />

Major Component Parts<br />

The major parts of the Cam Clutch are the cams, inner race, outer race, springs and bearings. Each of these<br />

parts play an important role in the function of the Cam Clutch. All parts are made of carefully selected materials,<br />

have undergone appropriate heat treatment, and have passed strict quality control checks.<br />

Part<br />

Cam<br />

Appearance<br />

Function<br />

A number of cams set regularly in between the inner and outer races function<br />

as props or sliders depending on the relative rotating directions of the inner and<br />

outer races. This action causes engagement (clutching) and disengagement<br />

(overrunning) of the clutch inner and outer races.<br />

The cams are the vital component of a Cam Clutch, and they are available in<br />

various models and types to suit a variety of applications.<br />

Inner Race<br />

Outer Race<br />

The inner and outer sliding faces of the races are hardened and precisionground<br />

into a perfectly round cylinder to enable them to withstand the<br />

compressive stress generated during engagement with the cam and sliding<br />

abrasion when overrunning.<br />

Spring<br />

Compressed springs are set at both ends of the cams to ensure that all of the<br />

cams contact the inner and outer races at all times. Thus, the cams are always<br />

ready for immediate engagement. This is extremely important so as to ensure<br />

that the load is spread evenly across all cams when they engage with the inner<br />

and outer races.<br />

Bearing<br />

The bearings maintain concentricity of the inner and outer races and bear the<br />

radial load for the engagement of the cams and the inner and outer races.<br />

Maintaining concentricity is particularly important to ensure that the load is<br />

spread equally and simultaneously over the cams at the time of engagement.<br />

■ BR SERIES CONSTRUCTION<br />

NON-CONTACT DESIGN EXTENDS SERVICE LIFE<br />

Greatly Increased Service Life<br />

Made possible by <strong>TSUBAKI</strong>’s extensive experience in mechanical<br />

power transmission, the cam used in the BR Cam Clutch offers a<br />

unique cross section that provides positive mechanical<br />

engagement only when needed. Otherwise, the Cam Clutch rotates<br />

freely with absolutely no mechanical contact in the clutch<br />

mechanism. The result is a greatly increased service life compared<br />

to conventional types.<br />

Backstop applications with high-speed overrunning<br />

When the Cam Clutch is stationary, the cam locks the<br />

inner and outer races together (figure 1). When the<br />

inner race (load side) overruns at a high speed, the<br />

cam disengages by releasing from the inner race<br />

(figure 2). When the inner race stops, the cam rotates<br />

back into an engaged position. If the inner race tries<br />

to rotate in the reverse direction, the cams then serve<br />

as a prop between the anchored outer race and inner<br />

race to prevent the reverse rotation and provide<br />

backstopping.<br />

High-speed and low-speed-engaged overrunning<br />

When the Cam Clutch is stationary, the cam locks the<br />

inner and outer races together (figure 1). When the<br />

inner race (load side) overruns at a high speed, the<br />

cam disengages by releasing from the inner race<br />

(figure 2). When the high-speed rotation of the inner<br />

race stops and the inner race begins to rotate slowly,<br />

the cam rotates back into an engaged position. Then<br />

when you start to drive the outer race at low speed of<br />

rotation, the cams serve as a prop and drive the inner<br />

race at the same low speed of rotation.<br />

A more economical design.<br />

The open-type BR series features a simple design in<br />

which the Cam Clutch mechanism is incorporated in a<br />

cage between standard dimension inner and outer<br />

bearing races. This allows the Cam Clutch to be easily<br />

and economically integrated into a wide variety of<br />

mechanical systems. A package-type Cam Clutch is<br />

also available to reduce maintenance demands.<br />

■ MODES OF OPERATION<br />

<strong>TSUBAKI</strong> Cam Clutches are precision devices which lock to transmit torque in one direction of rotation, but<br />

overrun (freewheel) in the opposite direction of rotation. All the series of clutches utilize the same principles of<br />

operation. Since clutch applications encompass a variety of load and speed characteristics, <strong>TSUBAKI</strong> Cam<br />

Clutches are manufactured in a range of capacities and styles, which are designed to provide the best functional<br />

characteristics for performing in the following three basic modes of operation:<br />

1. General overrunning<br />

Clutches used in this type of application overrun at<br />

either the inner or outer race during the majority of the<br />

clutch operating time, and are occasionally called<br />

upon to lock up and drive. A typical application is a<br />

two-speed drive, where an electric motor and a<br />

geared motor are connected to a single driven shaft<br />

through one-way clutches. The machine can be driven<br />

by either the electric motor or geared motor. When the<br />

geared motor drives at low speed, the clutch<br />

engages. When the electric motor drives the machine,<br />

the clutch overruns. The clutch automatically switches<br />

between low speed and high speed.<br />

2. Indexing<br />

In this mode of operation, reciprocating motion<br />

applied to the driving race of the clutch is transformed<br />

into unidirectional intermittent motion, at the driven<br />

race. For example, on a feeding roller, the clutch is<br />

mounted on the roller and a torque arm is connected<br />

to the driving race of the clutch. A crank motion<br />

mechanism provides reciprocating motion to the<br />

driving race. The clutch drives in the forward stroke<br />

(index) and overruns on the return stroke, resulting in<br />

intermittent unidirectional motion of the feeding roller.<br />

3.Backstopping<br />

In backstop applications, the clutches are used to<br />

prevent reverse rotation of drive shafts, which may<br />

cause damage to machinery and other expensive<br />

equipment. With the outer race of the clutch anchored<br />

stationary, the inner race can overrun freely in one<br />

direction of rotation. Reverse rotation is<br />

instantaneously prevented by the automatic<br />

engagement of the clutch. Typical backstop<br />

applications are in conveyor systems and gear<br />

reducers.<br />

USE IN VARIOUS APPLICATIONS<br />

To select the optimum Cam Clutch, it is imperative that you thoroughly understand the application and conditions<br />

of use. The following explains the use of Cam Clutches by application: First confirm how the clutch you are going<br />

to use is classified, and then obtain detailed data from the relevant pages.<br />

A. OVERRUNNING<br />

Cam behavior and Cam Clutch operation<br />

In the case of a Cam Clutch<br />

similar to the one shown on<br />

the right, the different<br />

conditions of engagement<br />

and disengagement for the<br />

various possible states are<br />

described below. These<br />

states are referred to as<br />

“overrunning”.<br />

1. Outer race rotates counterclockwise.<br />

1-1<br />

When the outer race starts<br />

rotating counterclockwise from a<br />

standstill at N0 r/min, the Cam<br />

Clutch engages and the inner<br />

race rotates in the same<br />

direction at N0 r/min.<br />

1-2<br />

When the inner race is rotated<br />

counterclockwise at N1 r/min by<br />

an outside force in the above<br />

state, and if N1 is faster than N0<br />

(N1>N0), the Cam Clutch<br />

overruns and the inner race<br />

rotates at N1 r/min, and the outer<br />

race at N0 r/min.<br />

1-3<br />

When N1 and N0 become equal,<br />

either by deceleration of N1 or<br />

by acceleration of N0, the Cam<br />

Clutch engages again, and this<br />

continues as long as N0 is faster<br />

than N1 (N1

A-1. DUAL DRIVE AND TWO-SPEED DRIVE<br />

Dual drive is a drive system in which two sets of<br />

driving units are installed instead of one driven unit,<br />

and the driven unit is driven by one or both of them as<br />

required. With dual drive, a drive system which has<br />

two sets of driving units having different speeds of<br />

rotation is referred to as “two-speed drive”, and the<br />

driven unit is driven at either high or low speed.<br />

Normally, each driving unit uses one Cam Clutch<br />

which works as an automatic switcher for the driving<br />

units. In the figure on the right, when the driven unit is<br />

to be driven by driving unit A in the direction of the<br />

arrow, Cam Clutch A engages to transmit the rotating<br />

power of the outer race to the inner race i.e., to the<br />

driven unit, and drives it at a preset speed of rotation.<br />

At this point, since the inner race of Cam Clutch B<br />

which is connected to the driven unit also rotates in<br />

the direction of the arrow, Cam Clutch B does not<br />

engage but overruns, thus disconnecting the driving<br />

unit B from the driven unit. Conversely, when the<br />

driven unit is to be driven by driving unit B in the<br />

direction of the arrow, Cam Clutch B engages to<br />

transmit the rotating power of the outer race to the<br />

inner race, i.e., to the driven unit, and drives it at a<br />

preset speed of rotation. At this time, Cam Clutch A<br />

overruns to disconnect driving unit A. Cam Clutch<br />

applications are divided into four types (as indicated<br />

in the table on the right) depending on the<br />

overrunning speed and the engaging speed.<br />

A-1-1. High-Speed Overrunning and High-Speed Engagement<br />

(Overrunning speed = 700 r/min and up)<br />

(Engaging speed = 700 r/min and up)<br />

Example of fan or pump drive<br />

This example shows a high-speed system in which a<br />

driven unit (pump or fan) is driven by a dual drive<br />

system consisting of a motor and a turbine. The Cam<br />

Clutches are used for automatic switching between<br />

the driving units. The fan is normally driven by the<br />

Cam Clutch on the turbine side. When starting, or<br />

when steam pressure to the turbine drops, the motor<br />

takes over from the turbine to drive the fan. Cam<br />

Clutch A engages when the turbine drives the fan, and<br />

it overruns when the motor drives the fan. Conversely,<br />

Cam Clutch B overruns when the turbine drives the<br />

fan, and it engages when the motor drives the fan.<br />

The driving devices can be changed over without<br />

switching the clutch. This is because the difference in<br />

the speed of rotation between the motor and turbine<br />

turns the Cam Clutches on and off, and the driving<br />

device rotating the fastest is connected automatically<br />

to the driven unit. Overrunning and engagement of the<br />

Cam Clutches are performed continuously at speeds<br />

faster than 700 r/min.<br />

A-1-2. High-Seed Overrunning and Medium and<br />

Low-Speed Engagement<br />

(Overrunning speed = 700 r/min and up)<br />

(Engaging speed = up to 700 r/min)<br />

Example of energy saving drive for a soaking pit fan<br />

Application of Cam Clutches in an energy saving<br />

pump (power recovery system) shows how highly<br />

effective energy saving can be achieved with the aid<br />

of Cam Clutches. The motor-driven pump discharges<br />

high-pressure liquid, which, after circulating, is used to<br />

drive a turbine. The turbine is then used to help drive<br />

the pump. If the pressure available is too low to rotate<br />

the turbine at high speed, the Cam Clutch overruns.<br />

However, when the rotating speed of the turbine<br />

reaches the rotating speed of the motor, the Cam<br />

Clutch engages automatically and the pump is driven<br />

by both the turbine, and the motor. Thus, power<br />

consumption equivalent to the turbine output can be<br />

saved. Since energy loss during overrunning and<br />

engagement of the Cam Clutch is extremely small, this<br />

system produces results for pumps with an output as<br />

low as 7.5 kW. Setup requires only installation of a<br />

Cam Clutch and a turbine, and provides a highefficiency<br />

energy recovery system with low running<br />

costs.<br />

The Cam Clutch works as a switcher for two driving<br />

units (high-speed or medium/low-speed). When driving<br />

a fan, cement kiln or conveyor in normal operation, the<br />

driving speed is switched to high speed. When using<br />

them for other purposes, the driving speed is switched<br />

to medium or low-speed. The figure above shows a<br />

soak pit fan used for melting aluminum and steel<br />

ingots, with a Cam Clutch being used for energy<br />

saving. The heating is done in two stages, one being<br />

quick heating and the other being constant heating.<br />

Switching is done automatically by a driving system.<br />

For quick heating, the fan is driven by the main motor<br />

at high speed (the Cam Clutch is overrunning at this<br />

time). For constant heating, since the fan only rotates<br />

at low speed, it is driven by a geared motor (the Cam<br />

Clutch engages and the main motor and fan rotate<br />

simultaneously). Compared to pole change or inverter<br />

systems, great equipment cost savings can be made,<br />

and the initial equipment costs can be recovered very<br />

quickly. If equipment costs must be recovered within<br />

one year of continuous running, this system is effective<br />

for fans from the 15 kW class and up.<br />

Smoke ventilation and gas mixing fans operate in high<br />

temperature environments. In order to prevent<br />

excessive thermal transfer from distorting the fan<br />

shaft, an auxiliary drive system is used to keep the<br />

fans rotating slowly when the main motor shuts down.<br />

Using a Cam Clutch at the auxiliary motor eliminates<br />

the need for manual clutch operation. Thermal<br />

expansion in the fan shaft must be absorbed through<br />

an expandable coupling. During main motor<br />

operation, the Cam Clutch rotates as a normal<br />

bearing, so service life is greatly extended.<br />

Turbine Auxiliary Drive Systems<br />

This example shows a Cam Clutch installed in the<br />

auxiliary drive system of a steam turbine. The auxiliary<br />

drive system powers the turbine at low speed through<br />

the engaged Cam Clutch, until steam pressure<br />

accelerates the turbine to the Cam Clutch release<br />

speed. Then the cam automatically disengages and<br />

runs as a high speed ball bearing, because there is<br />

no mechanical contact in the clutch.<br />

Medium and Low-Speed Engagement<br />

(Overrunning speed = Up to 700 r/min)<br />

(Engaging speed = Up to 700 r/min)<br />

In this application, one driven unit is driven at twospeeds<br />

by two medium and low-speed drive units,<br />

both at speeds lower than 700 r/min. Two Cam<br />

Clutches enable automatic switching between the<br />

drive units.<br />

Example of pasting roll drive<br />

The above figure shows an example of Cam Clutches<br />

being used with the pasting rolls of a corrugating<br />

machine for making cardboard. The pasting rolls are<br />

driven continuously by the main motor. During this<br />

time, Cam Clutch A engages and Cam Clutch B<br />

overruns. When the main motor must be stopped<br />

temporarily to fix a problem, it is necessary to keep<br />

rotating the pasting rolls in order to prevent paste on<br />

the roll surface from drying. To do this, the rolls are<br />

driven by an auxiliary motor at a low speed sufficient<br />

to prevent the paste from drying (Cam Clutch A<br />

overruns, while B engages). This system is also used<br />

with meat choppers and screw feeds in food<br />

processing machinery.<br />

A-2. NORMAL ENGAGEMENT REVERSE<br />

OVERRUNNING<br />

In this application, the normal rotating input power is<br />

held for a certain time and, after driving the driven<br />

side through the engagement of the Cam Clutch, the<br />

Cam Clutch is put into the overrunning state by<br />

reversing the input power. This application is classified<br />

into the following three kinds, depending upon the<br />

purpose for overrunning the Cam Clutch:<br />

1. To simply break the linkage between the input side<br />

and the driven unit (for details, see A-2-1 below).<br />

2. To make the driven unit rotate in reverse by drive<br />

from another source after making the input side<br />

rotate in reverse, and brake the load by<br />

engagement of the clutch when the speed of<br />

rotation of the driven unit has reached that of the<br />

input side (for details, see A-2-2 below).<br />

3. To selectively drive either one of the driven units A<br />

or B connected respectively to the outer races of<br />

the different aligned Cam Clutches A and B, which<br />

are connected to the same drive shaft. When Cam<br />

Clutch A engages due to normal rotation of the<br />

shaft, Cam Clutch B overruns, and when Cam<br />

Clutch B engages due to reverse rotation of the<br />

shaft, Cam Clutch A overruns (for details, see A-2-3<br />

below).<br />

A-2-1. Application requires breaking connection<br />

only (see the figure below)<br />

This example shows the use of a Cam Clutch with an<br />

inclined pump. If the motor is wired in reverse by<br />

mistake at installation, it will rotate the pump in reverse.<br />

By mounting a Cam Clutch between the motor and the<br />

pump, reverse rotation of the pump (which must not be<br />

allowed) is prevented because the Cam Clutch will<br />

overrun if the motor rotates in reverse. The Cam Clutch<br />

stays engaged at all times when the rotation is normal.<br />

A-2-2. Application for the purpose of braking the<br />

driven side (see the figure below)<br />

The example here shows an application in which the<br />

hose drum of a pipe flusher is being driven. When the<br />

hydraulic motor is rotated in reverse in the<br />

counterclockwise direction, the Cam Clutch inner race<br />

rotates in reverse, and the Cam Clutch overruns. The<br />

flushing pump is driven in this state. The flushing water<br />

passes through the hose and gushes out of the nozzle<br />

toward the back. The force of this water jet starts the<br />

nozzle running and pulls and unwinds the hose. At the<br />

same time, the hose drum starts reverse rotation in the<br />

same counterclockwise direction, and increases its<br />

speed of rotation until it reaches the overrunning speed<br />

of the inner race. At this point, the Cam Clutch<br />

engages, and the hydraulic motor works as a brake to<br />

stop the acceleration of the drum. Therefore, the<br />

running speed of the water jet nozzle is kept constant<br />

thereafter. When the hydraulic motor is rotated normally<br />

in the clockwise direction, the Cam Clutch engages to<br />

wind the unwound hose onto the drum.<br />

A-2-3. Application for the purpose of selectively<br />

driving either one of two driven units by<br />

normal or reverse rotation of the drive input<br />

(see the figure below)<br />

When the motor is rotating normally (in the<br />

counterclockwise direction), Cam Clutch A engages to<br />

drive unit A, and Cam Clutch B overruns. Conversely,<br />

when the motor is rotated in reverse (in the clockwise<br />

direction), Cam Clutch B engages to drive driven unit<br />

B. In this application, the two driven units must work<br />

independently.<br />

A-3. FREE WHEELING<br />

To prevent differences in the rotating speed between the<br />

driving side and the driven side from damaging the<br />

driving unit or the product, the Cam Clutch overruns<br />

when speed differences occur. Normally, the Cam Clutch<br />

engages to transmit torque, and it overruns to break the<br />

connection between the driving side and the driven side.<br />

In this case the Cam Clutch overruns at a speed equal to<br />

the difference in rotating speed that occurs when the<br />

driven unit (normally the inner race) rotates faster than<br />

the driving unit (normally the outer race), or when the<br />

driving unit is decelerated or stopped abruptly.<br />

When feeding hoop-shaped material or plate material to<br />

the next process by slitter or pressure rolls, the material is<br />

fed at first by pinch rolls up to the main rolls. Since the<br />

main rolls process the material while pulling it at a speed<br />

faster than that of the pinch rolls, the pinch rolls are<br />

pulled by the material. At this point, the Cam Clutch<br />

starts to overrun and prevents the pinch rolls from being<br />

driven in reverse by the material. The Cam Clutch is used<br />

to prevent damage to the pinch roll driving parts and to<br />

the material, due to slippage between the pinch rolls.<br />

This method is also used with drying machines, engine<br />

testers, and plywood fabricating machines.<br />

A-4. MANUAL TYPE<br />

Cam Clutches are used when a machine is operated<br />

manually for positioning, adjustment or inching. The<br />

Cam Clutch mounted at the manual handle overruns<br />

while the machine is in operation. The handle does not<br />

rotate and cause a safety hazard.<br />

Cam Clutches are used in the manual handles of<br />

circular knitting machines. The manual handle is used<br />

to operate the machine manually when starting, for<br />

adjustment of the needle and thread. When the<br />

machine starts its regular knitting work after the<br />

adjustment, the linkage between the Cam Clutch and<br />

the handle is broken. Another Cam Clutch is provided<br />

at the output section of the worm reduction gears, to<br />

break the connection with driving side during manual<br />

operation. Since this Cam Clutch engages to drive the<br />

circular knitting machine during regular operation, the<br />

large torque capacity PB12 is used.<br />

In this application, reciprocal movement of a certain<br />

angle (θ) is provided at the outer race of the Cam<br />

Clutch to perform engagement and overrunning in turn<br />

continuously and obtain intermittent rotation. In the case<br />

of the Cam Clutch shown in the figure, when the outer<br />

race moves from A to B, the<br />

Cam Clutch engages to<br />

rotate the inner race (of the<br />

driven side) by angle θ, i.e.,<br />

from a to b. However, the<br />

Cam Clutch does not<br />

operate to stop the inner<br />

race at position b. When the<br />

outer race rotates in reverse<br />

from B to A, the Cam Clutch<br />

overruns while the inner race<br />

(of the driven side) does not rotate. By repeating this<br />

sequential movement, the inner race (of the driven side)<br />

rotates intermittently within the preset angle (θ).<br />

The example in the figure shows a roll feeding device<br />

which is frequently used in high-speed automatic<br />

clamp presses. Driving power is taken out of the<br />

eccentric disk provided at the end of the continuously<br />

rotating crankshaft, and this power drives the feed<br />

rolls intermittently through a Cam Clutch. The feed<br />

length can be changed quickly and easily for<br />

improved work efficiency. In order to attain highspeed,<br />

high-precision feeding, a cone brake with less<br />

torque fluctuation and a Cam Clutch for backstopping<br />

are used together.<br />

The Cam Clutches in this application are designed for<br />

use in the range of (N × θ) ≤ 20,000. Please consult<br />

<strong>TSUBAKI</strong> regarding clutches for use outside of this<br />

range.<br />

Indexing in this application range is applicable to<br />

many machines. The figure shows an example of use<br />

in the paper feeding section of an automatic stapler.<br />

The reciprocating movement of the eccentric disk is<br />

converted by the Cam Clutch into an intermittent feed<br />

motion, which drives the belt conveyor. Hence,<br />

stapling is timed to the intermittent feeding motion and<br />

load overrun is prevented by a brake. Stapling is done<br />

at an exact pitch. This indexing can be applied<br />

extensively to food and other packaging machines.<br />

Segmented gears and rack & pinions are often used<br />

to produce the reciprocal movement to be transmitted<br />

to the Cam Clutch. The figure below gives an<br />

application example of a pouch making machine.<br />

Since the reciprocal movement of the eccentric disk is<br />

accelerated through the rack & pinion assembly, the<br />

reciprocal action of the Cam Clutch outer race is<br />

enlarged to 860°. In this machine, the 60 mm vinyl<br />

sheet feeding length is indexed at a speed of 40 to 60<br />

times per minute. In this case, the acceleration of the<br />

Cam Clutch increases, a large torque acts repeatedly,<br />

and the cam slipping distance at overrunning<br />

becomes longer. Hence, a cam is required that has<br />

superior engagement and higher anti-abrasive<br />

properties. A brake is used in order to improve the<br />

precision of the vinyl sheet feeding pitch.<br />

B-4. BACKSTOPPING IN INTERMITTENT<br />

FEEDING<br />

Cam clutch and feed accuracy<br />

When designing a high-accuracy feeding device that<br />

incorporates Cam Clutch indexing, both the driving<br />

and driven units must be made light in weight and high<br />

in rigidity. Moreover, when selecting the ideal Cam<br />

Clutch, it is extremely important to select a brake to<br />

stop the driven unit at a preset position, a positioning<br />

device, and a Cam Clutch for backstopping (which<br />

cannot be expected of the Cam Clutch for indexing).<br />

Feed accuracy = Cam Clutch for indexing +<br />

Cam Clutch for backstop + Brake<br />

Cam Clutch for backstopping<br />

This Cam Clutch overruns<br />

when the Cam Clutch for<br />

indexing has completed one<br />

feeding stroke. If the frictional<br />

resistance of the driven unit<br />

is smaller than the<br />

overrunning frictional torque<br />

of the Cam Clutch, or if a<br />

reverse torque occurs on the<br />

driving side due to back<br />

MX Series<br />

tension of the material, the<br />

driven unit may rotate in reverse without stopping at<br />

the end point fed by the Cam Clutch. The most<br />

effective way to prevent this is to mount a Cam Clutch<br />

for backstopping, although a brake or positioning pin<br />

may also be used for this purpose. Since the Cam<br />

Clutch for backstopping repeats the overrunning and<br />

engagement at the same frequency as that of the Cam<br />

Clutch for indexing, use one that is equivalent to the<br />

feeding clutch or one that is one size smaller.<br />

Brakes and other stopping devices<br />

The outer race of a Cam<br />

Clutch for indexing starts<br />

reverse rotation immediately<br />

upon the completion of one<br />

feeding stroke. At the same<br />

time, the Cam Clutch starts<br />

overrunning. At this moment,<br />

the driven unit is free from all<br />

restrictions, and therefore,<br />

when the driven unit has a<br />

Cone brake<br />

larger inertia or the feed<br />

speed is faster, the inner race tends to rotate beyond<br />

the stroke of the outer race. To prevent this, a friction<br />

brake is often used as a braking device, although a<br />

positioning pin or stopper may also be used for this<br />

purpose. A braking device significantly improves the<br />

feed accuracy. Accordingly, use a frictional brake which<br />

has as small a fluctuation as possible in its braking<br />

force. The wet-type cone brake is most effective. Please<br />

consult <strong>TSUBAKI</strong> regarding brake selection.<br />

B-5 FEEDING WITH STOPPER<br />

(Feed frequency = Up to 300 times/min.)<br />

(Feed angle = up to 90°)<br />

In this application, a stopper forcibly stops the material<br />

to be indexed at a position just before the feed end<br />

point, to obtain a fixed feeding pitch. As soon as the<br />

material hits the stopper, a shock torque larger than the<br />

torque required for feeding is applied to the feeding roll<br />

which is still rotating. The figure below shows an<br />

example of a Cam Clutch used in a bolt header. The<br />

wire is fed intermittently by a Cam Clutch mounted on<br />

a grooved feed roll. Since the feed length of the wire is<br />

set longer than necessary, the fed wire hits the stopper<br />

which has been set at a position where the wire can be<br />

fed at the necessary length. The reactive force this<br />

generates acts as vibrating shock load upon the Cam<br />

Clutch. It is therefore necessary to consider this when<br />

selecting a Cam Clutch.<br />

Example of bolt header<br />

Applicable series<br />

Consult <strong>TSUBAKI</strong>.<br />

Cautions<br />

When setting the feed length, consider the following:<br />

Feed length setting = Necessary length + α<br />

The closer to zero α is, the smaller the vibrating shock<br />

load on the Cam Clutch becomes and consequently,<br />

the longer the service life becomes.<br />

B-6. SPEED CHANGE<br />

(Feed frequency : N = Up to 300 times/min.)<br />

(Feed angle : θ = Up to 90°;N ×θ= 20,000 max.)<br />

In an intermittent feed mechanism that uses one or<br />

more Cam Clutches, the speed of the driven side is<br />

changed steplessly by changing the feed angle. The<br />

figure below shows an example of a sprinkler (manure<br />

spreader). The amount of manure to be sprinkled,<br />

which varies depending on the field conditions, must<br />

be adjusted case by case. The chain conveyor is<br />

driven by an intermittent Cam Clutch feeding action<br />

and the manure loaded on the cart is fed in bits to the<br />

sprinkling vanes, which rotate continuously. The<br />

manure to be sprinkled can thus be kept at the<br />

optimum amount by adjusting the amount of manure to<br />

be fed. The feed amount (or angle of the Cam Clutch)<br />

can be controlled steplessly while the sprinkler is<br />

operating.<br />

C. BACKSTOPPING TO PREVENT REVERSE ROTATION<br />

Backstopping is used to<br />

prevent the rotating shaft from<br />

rotating in the reverse direction.<br />

The Cam Clutch continues<br />

overrunning while the shaft<br />

rotates normally, and it<br />

engages to prevent reverse<br />

shaft rotation just before it is<br />

about to occur.<br />

Behavior and function of<br />

Cam Clutch<br />

Normally, the inner race is<br />

mounted on the rotation shaft,<br />

and the outer race is fixed to<br />

the machine frame. The inner<br />

race is thus set on the<br />

overrunning side. As soon as<br />

the shaft begins to rotate in<br />

reverse, the cams engage with<br />

the inner and outer races to<br />

prevent reverse rotation and<br />

support the load.<br />

Prevention of reverse rotation of inclined and vertical<br />

conveyors is a typical example of how backstopping<br />

is used. The following A, B, and C types are available<br />

for different Cam Clutch mounting positions, and the<br />

C-1. BACKSTOPPING FOR LOW-SPEED<br />

OVERRUNNING<br />

(Overrunning speed at 150 r/min or less)<br />

In this application, the inner race<br />

of the Cam Clutch is mounted<br />

directly onto the conveyor head<br />

pulley, or other shaft with a lowspeed<br />

of rotation, while the outer<br />

race is anchored to the conveyor<br />

frame to prevent reverse rotation.<br />

Since reverse rotation is prevented directly by the<br />

conveyor shaft without using a drive chain, gears, or<br />

couplings, this is regarded as the safest and most reliable<br />

mounting method. Additionally, a low overrunning speed<br />

minimizes the cam overrunning slip speed, as well as the<br />

overall slipping distance. As a result, wear on the cam is<br />

reduced and a prolonged service life can be expected.<br />

In addition to conveyors, this system is also used to<br />

prevent reverse rotation in inclined and screw pumps.<br />

C-2. BACKSTOPPING FOR MEDIUM-<br />

(Overrunning speed = 150 to 700 r/min)<br />

In this application, the Cam Clutch is mounted on shafts<br />

rotating at medium speeds, such as the intermediate<br />

shafts of reduction gears, etc., to prevent reverse rotation.<br />

Since reverse rotation is prevented by the medium-speed<br />

shaft, the Cam Clutch required only needs to withstand a<br />

comparatively small torque which is inversely<br />

proportional to the rotating speed ratio of the conveyor<br />

shaft. Accordingly, even a small-sized Cam Clutch can<br />

be used for this purpose.<br />

This example shows a Cam Clutch installed to a motor<br />

pulley to prevent reverse rotation. Cam Clutches can<br />

be installed to inclined belt conveyor systems to<br />

prevent reversing when the conveyor stops, as a result<br />

There are many cases in which large scale vertical<br />

motor or pump systems must be kept from turning<br />

backwards A Cam Clutch can be installed above the<br />

motor of a vertical motor system, or on the mainshaft<br />

of a vertical pump, to provide this function. Anchoring<br />

the outer race of the Cam Clutch will prevent the inner<br />

race from rotating in the reverse direction.<br />

Many liquid media transmission systems use multiple<br />

pumps or compressors feeding into the same line, to<br />

save energy or provide emergency backup functions.<br />

System pressure will often cause the pump or<br />

compressor to back-spin when not running. A Cam<br />

Clutch can prevent this.<br />

For reasons of safety, belt conveyors must be<br />

prevented from moving backwards. Installing a Cam<br />

Clutch on the main motor shaft is the easiest and most<br />

economical method for this. For certain large and midscale<br />

belt conveyors with high lift distances, it may be<br />

more economical to install the Cam Clutch on one of<br />

the high speed shafts. In these cases it is important to<br />

verify the torque load applied to the engaged clutch.<br />

Installation and Usage<br />

1. MZ Series Cam Clutch is<br />

Shielded by shield bearings on<br />

both ends, packed with a special<br />

grease, and are ready for use. No<br />

additional lubricant is required.<br />

2. For attaching pulleys, gears or<br />

sprockets to the clutches, insert<br />

hubs (with f7 tolerance of ISO<br />

R773) along the inner surface of<br />

the outer race and screw the<br />

bolts (high tension) into the<br />

tapped holes on the clutch end.<br />

3. Recommended shaft tolerances<br />

are shown in the table on the<br />

lower left.<br />

4. External thrust load should be<br />

supported by other devices, not<br />

by the Cam Clutch.<br />

5. Use only a parallel key to secure<br />

the clutch to the shaft. Do<br />

Typical installation drawing<br />

not use a tapered Key.<br />

6. When mounting the clutch<br />

onto the shaft, apply<br />

pressure to the inner race<br />

but never to the outer<br />

race. See the illustration<br />

on the right.<br />

7. For vertical mounting,<br />

please consult <strong>TSUBAKI</strong>.<br />

8. Ambient temperature<br />

range is –5° to 40°C.<br />

9. Key to be used should be<br />

in accordance with ISO<br />

R773. (DIN 6885.1)<br />

Installation and Usage<br />

1. When mounting sprockets or gears to the outer<br />

race, use the outer race outer dimension<br />

(dimension B) to make a centering flange in the<br />

gear or sprocket. Then attach firmly with bolts of<br />

tensile strength 10.9 or greater to the tapped holes<br />

in the outer race.<br />

2. Please refer to MZ Series for usage and other types<br />

of installations.<br />

Installation and Usage<br />

1. Model No’s. MZEU12 to MZEU80 are pre-greased and require no lubrication. The<br />

operational temperature range is –40°C to +40°C.<br />

Model No’s. MZEU90 to MZEU150 require oil lubrication. (Refer to lubrication and<br />

maintenance on page 31).<br />

2. Model No’s. MZEU12 to MZEU80 sprockets and other torque transmitting factors can be<br />

used with the standard flange. Refer to installation example 1.<br />

3. We recommend a Shaft tolerance of h7, and ISO R773 (DIN 6885.1) keyway is standard.<br />

4. We recommend a tolerance of E H7 for the sprocket and other parts.<br />

5. Clean the surface of both ends of the outer race and the contact surfaces of the flange,<br />

sprocket and the other parts.<br />

6. For Model No’s. MZEU90 to MZEU150, apply seal adhesive to the surface of the outer<br />

race at both ends.<br />

7. Check the direction of rotation.<br />

8. When installing standard flanges, sprockets and other equipment to the clutch fit them<br />

around the bearings and screw the bolts into both ends of the outer race.<br />

9. By installing both the flange and sprocket on the opposite side, the direction of rotation<br />

can be changed.<br />

10. When mounting the clutch onto the shaft, apply pressure to inner race but never to the<br />

outer race.<br />

11. For high speed Indexing applications (More than 50 c/m) a strong spring type is<br />

recommended.<br />

Installation and Usage<br />

1. Model No’s. MZEU12 to MZEU80 are pre-greased and require no lubrication. The<br />

operational temperature range is –40°C to +40°C.<br />

Model No’s. MZEU90 to MZEU150 require oil lubrication. (Refer to lubrication and<br />

maintenance on page 31).<br />

2. We recommend a Shaft tolerance of h7, and ISO R773 (DIN 6885.1) keyway is standard.<br />

3. We recommend tolerances of B H7 or H8 for sprockets, gears and other fitted parts.<br />

4. The clutch is delivered with a Basic type Cam Clutch, E1 flange and E2 flange as<br />

separate parts.<br />

5. Clean the surface of both ends of the outer race and the contact surfaces of the flanges.<br />

6. For Model No’s. MZEU90 to MZEU150, apply seal adhesive to the surface of the outer<br />

race at both ends.<br />

7. Check the direction of rotation and attach the E1 and E2 flanges to clutch.<br />

8. When installing sprockets, gears and other equipment to the clutch, fit them on the<br />

surface of the outer race and screw the bolts into the E1 flange.<br />

9. By installing both the flange and sprocket on the opposite side, the direction of rotation<br />

can be changed.<br />

10. When mounting the clutch onto the shaft, apply pressure to inner race but never to the<br />

outer race.<br />

11. For high speed Indexing applications (More than 50 c/m) a strong spring type is<br />

recommended.<br />

Installation and Usage<br />

1. Model No’s. MZEU12 to MZEU80 are pre-greased and require no<br />

lubrication. The operational temperature range is –40°C to +40°C.<br />

Model No’s. MZEU90 to MZEU150 require oil lubrication. (Refer to<br />

Grease lubrication<br />

lubrication and maintenance on page 31).<br />

2. We recommend a Shaft tolerance of h7, and the DIN 6885.1 keyway is<br />

standard.<br />

3. The clutch is delivered with a Basic type Cam Clutch, E3 torque arm and<br />

E4 cover as separate parts.<br />

4. Clean the surface of both ends of the outer race and the contact surface<br />

of E3 torque arm and E4 cover.<br />

5. For Model No’s. MZEU90 to MZEU150, apply seal adhesive to the<br />

surface of the outer race at both ends.<br />

6. Check the direction of rotation and attach the E3 torque arm to the clutch.<br />

7. By installing both the flange and sprocket on the opposite side, the<br />

direction of rotation can be changed.<br />

8. When mounting the clutch onto the shaft, apply pressure to inner race<br />

but never to the outer race.<br />

9. For Model No’s. MZEU12 to MZEU80, before mounting the E4 cover to the<br />

clutch attach the end plate with bolts. Refer to installation example 4.<br />

From MZEU12 to MZEU80<br />

10. For Model No’s. MZEU90 to MZEU150, before mounting the cover attach<br />

the packing and end plate using sealing washers and bolts. Refer to<br />

installation example 5.<br />

Installation and Usage<br />

1. The clutch is delivered with a Basic type Cam Clutch, two E5<br />

flanges, and flange kit as separate parts.<br />

2. Check the direction of rotation and attach an E5 flange to the<br />

clutch by the bolt.<br />

3. When installing sprocket, gear and other equipment to the<br />

clutch, install them on the outer race and fix the key between<br />

the equipment and the outer race.<br />

4. We recommend a tolerance of H7 for the bore of the sprocket,<br />

gear or other equipment.<br />

5. Attach the opposite side E5 flange to the clutch by the bolts.<br />

6. By installing the clutch to the shaft on the opposite side, the<br />

direction of rotation can be changed.<br />

7. When mounting the clutch onto the shaft, apply pressure to the<br />

inner race but never to the outer race.<br />

8. For high speed indexing applications (More than 50 c/min) a<br />

strong spring type is recommended.<br />

9. Refer to page 31 for other usage.<br />

10. E5+E5 flange is available only for MZEU K model.<br />

Installation and Usage<br />

1. The clutch is delivered with a Basic type Cam Clutch, E2 flange,<br />

E7 flange and each flange kit as separate parts.<br />

2. Check the direction of rotation and attach the each flange to the<br />

clutch.<br />

3. When installing sprocket, gear and other equipment to the<br />

clutch, fit them on the surface of the outer race or flange and<br />

screw the bolt in to them.<br />

4. By installing both option parts on the opposite side, the<br />

direction of rotation can be changed.<br />

5. When mounting the clutch onto the shaft, apply pressure to the<br />

inner race but never to the outer race.<br />

6. For high speed indexing applications (more than 50 c/min) a<br />

strong spring type is recommended.<br />

7. Refer to page 31 for other Usage.<br />

8. Model No. MZEU K<br />

No Mark : No keyway on the outer race.<br />

K : Keyway on the outer race.<br />

Notes: Do not apply a large overhung load to the outer race by<br />

using E7 flange to keep the centerline between the inner<br />

and outer race.<br />

Installation and Usage<br />

1. MZEU (K)-C series Cam Clutch couplings make use of MZEU (K) series and CR type couplings without cover.<br />

2. Mount the Cam Clutch loosely on the high speed shaft at first.<br />

3. Accurately align both sprockets by checking with a straight edge on the teeth of both sprockets.<br />

4. Check whether the clearance(S) between both sprokets are correct, then wrap the chainaround the sprockets.<br />

5. Specify right hand (RH) or left hand (LH) as inner race overrunning direction from the view of Cam Clutch side<br />

(*) See the above drawing.<br />

6. The same lubricaion as for Tsubaki roller chain is necessary for the coupling chain.<br />

7. Ensure that the chain is properly closed with a connecting link and that the closed of the spring clip is<br />

installed in the same direction as the rotation of the outer race.<br />

Drawing to explain about lubrication<br />

1. Apply a suitable amount of oil before use.<br />

2. As a general rule, the amount of lubricant should be level with the center of the shaft for overrunning or backstopping.<br />

3. The E2 flange has three plugs. The E4 cover has a large plug for adding oil and two small plugs for checking and<br />

draining.<br />

4. Place the plugs, so that one is at the top and one is at the bottom. The center one should be level with the center of<br />

the shaft.<br />

5. Pour oil into the clutch until it overflows from check plug. After a few minutes, pour in more oil and check that it<br />

overflows again.<br />

Initially, replace oil after 10 hours of operation.<br />

Then replace it every 3 months.<br />

In a dirty environment, we recommend replacement every month.<br />

Installation and Usage<br />

1. 200 Series Cam Clutch is shaft<br />

mounted, so the shaft on which<br />

the clutch is mounted must be<br />

hardened to Rc 56-60 and 1.5 mm<br />

case depth after grinding. Grind to<br />

1.5S (16micro-inch) finish. The<br />

taper of this shaft should not<br />

exceed 0.01 mm per 50mm.<br />

2. For installation of the clutch,<br />

mount the clutch with bearings<br />

at both sides or on one side in<br />

order to obtain concentricity<br />

between the shaft and the clutch<br />

outer race and to take up radial<br />

or thrust loads which may work<br />

on the outer race or the shaft.<br />

See the installation example.<br />

3. The clutch should be mounted<br />

on the shaft by rotating it in the<br />

direction marked by the arrow<br />

shown on the clutch plate. Do<br />

not apply shock to the clutch by<br />

hammering.<br />

4. The clutches have the same<br />

outside diameters as the<br />

bearings shown in the table<br />

above. Bore tolerance of the<br />

housing in which the clutch is<br />

assembled should be within the<br />

range shown in the table below.<br />

5. For indexing, oil lubrication is<br />

recommended.<br />

6. Concentricity of the housing<br />

bore and shaft should be within<br />

0.05 mm.<br />

7. Key profile should be in<br />

accordance with JIS B1301-1959.<br />

BB series BB-1K-K series BB-2K-K series BB-2GD series BB-2GD 1K-K series<br />

General information of Installation and usage for BB series Cam Clutch<br />

1. BB series Cam Clutch is designed for press fit installation.<br />

2. BB-1K-K and BB-2GD 1K-K series have a keyway on the inner race. Keyways, except size 25 are<br />

manufactured to DIN 6885. 3, BB40-1K-K and BB40-2GD 1K-K are manufactured to DIN 6885. 1.<br />

3. BB-2K-K series has a keyway on both the inner and outer race.<br />

“-K” means keys shipped together with Cam Clutch.<br />

4. Correct interference dimensions at the shaft and the housing must be maintained to obtain maximum bearing<br />

and clutch performance.<br />

5. Refer to the table on next page for tolerance of the shaft and housing for each series.<br />

6. BB-2GD and BB-2GD 1K-K series have special lip seals for the effective protection against dust.<br />

7. The arrow on the inner race shows the direction of inner race engaging.<br />

8. To install the clutch, use a press tool of the appropriate diameter to apply even pressure over the entire face<br />

of the inner and outer race.<br />

9. Do not hammer or apply other shock to the clutch.<br />

10. Make sure the housing has enough strength to withstand the pressure required for the press fitting installation<br />

of the Clutch.<br />

11. Operating temperature range: –30°C to +100°C (Consult us for the temperature that exceeds this range).<br />

Lubrication<br />

1. Since grease is already applied before delivery, there is no need to apply grease before use.<br />

2. If the clutch is used with an oil lubricant, the oil lubrication should be applied inside the unit always.<br />

3. Do not use greases or lubricants with EP additives.<br />

Installation and Usage<br />

1. The outer race of the TFS Series Cam Clutch is designed for press fit installation to the housing. Correct<br />

interference dimensions of the outer race must be maintained to obtain maximum clutch performance.<br />

The internal diameter of the housing should meet the H7 tolerance. Keyways should be made in the end faces<br />

of the clutch for proper installation. Refer to item 3 in the installation and usage of BB Series Cam Clutch for<br />

information on the installation method. If the tolerance of the internal diameter of the housing is K6, keyways<br />

are not required on the end faces of the clutch.<br />

2. Make sure the housing has enough strength to withstand the pressure required for the press fitting installation<br />

of the clutch.<br />

3. When installing the clutch, mount it with a type 63 bearing to avoid radial force, since this clutch does not have<br />

any bearing support.<br />

4. The clutch should be mounted on the shaft by rotating it in the direction marked by the arrow shown on the<br />

clutch plate.<br />

5. The recommended shaft tolerate is H7, and the key profile<br />

should be in accordance with the following standard.<br />

TFS 12 ······DIN 6885. 1<br />

TFS 15 ~ 80 ······DIN 6885. 3<br />

6. Suitable surface pressure of the key should be selected<br />

according to your company design standards.<br />

Installation and Usage<br />

1. Concentricities of the inner race and the outer race<br />

are maintained by the plain bearing located<br />

between the outer race and the shaft. Radial load<br />

which works on the outer race is also supported by<br />

this plain bearing. The shaft must therefore be<br />

extended through the clutch outer race end.<br />

2. Recommended shaft tolerances are as follows:<br />

Typical installation drawing<br />

Model<br />

PB 3, PB 4,PB 6, PB 8<br />

PB 10, PB 12, PB 14<br />

Tolerance (mm)<br />

+0 to –0.013<br />

+0 to –0.016<br />

3. Do not use the PB Series Cam Clutch as a<br />

coupling. Use with a flexible coupling when<br />

connecting two shafts.<br />

4. Specify right (RH) or left hand (LH) inner race drive<br />

viewed from the end marked by the arrow in the<br />

illustration above. Check if the rotation of the clutch<br />

is correct before being run-in.<br />

5. For indexing use, oil lubrication is recommended.<br />

6. Key to be used should be in accordance with JIS<br />

B1301-1959<br />

7. Thrust load should be supported by other devices,<br />

not by the Cam Clutch.<br />

8. The bore of the driven member, such as the<br />

sprocket on the clutch outer race, should meet H6<br />

or H7 tolerance of the JIS standard.<br />

• When selecting the clutch, see “Information for Selection” on page 73.<br />

For lubrication, see “Lubrication and Maintenance”on page 75.<br />

Installation and Usage<br />

1. LD Series Cam Clutch is<br />

prelubricated with special<br />

grease and are ready for use.<br />

No additional lubricant is<br />

required.<br />

2. When installing the clutch on the<br />

shaft, press the clutch inner<br />

race slightly with a soft hammer<br />

to prevent the clutch outer race<br />

from slipping away from the<br />

inner race.<br />

3. Be sure to attach the plate. This<br />

prevents the outer race from<br />

slipping away from the inner<br />

race. See recommended<br />

dimensions of the plate listed on<br />

the right.<br />

4. For lubrication, coat the plate<br />

and thrust plate with grease.<br />

5. Never apply thrust loads to the<br />

clutch. Other devices should be<br />

provided to take up thrust loads<br />

applied to the clutch.<br />

6. Key should be in accordance<br />

with JIS B1301-1959.<br />

7. The bores of the pulley,<br />

sprocket, etc., should have a<br />

tolerance of H6 or H7.<br />

8. See “Information for Selection”<br />

Installation and Usage<br />

1. The bores of the pulley,<br />

sprocket, etc., should have a<br />

tolerance of H6 or H7.<br />

2. Built in roller type bearing, due<br />

to the structure of cam and<br />

roller.<br />

3. When installing the Cam Clutch<br />

on the shaft, press the clutch<br />

inner race slightly.<br />

4. Never apply thrust loads to the<br />

Cam Clutch. Other devices<br />

should be provided to take up<br />

thrust loads applied to the Cam<br />

Clutch.<br />

5. In case of large radial loads<br />

applied to the Cam Clutch like<br />

installing with pulley, another<br />

bearing should be prepared so<br />

that the point of the loads can<br />

be hanged on the bearing.<br />

6. Key should be in accordance<br />

with ISO R773 (DIN 6885.1).<br />

Note that the keyway<br />

dimensions of outer race is not<br />

in accordance with the keyway<br />

dimensions which mentioned in<br />

ISO R773 (DIN 6885.1).<br />

7. See “Information for lubrication<br />

and maintenance” on page 75.<br />

8. In case of using the Cam Clutch<br />

in a dusty atmosphere, or<br />

preventing the Cam Clutch from<br />

grease leakage, MDEU-2GD<br />

(Cam Clutch with dust seal type)<br />

is available as option.<br />

Note that the maximum<br />

overrunning speed of Cam<br />

Clutch with dust seal type is<br />

approximately 80% compared<br />

with that of the standard model.<br />

Installation and Usage<br />

1. For installation, insert the clutch<br />

into the hub bore of a pulley, a<br />

gear, or a torque arm and screw<br />

the bolts (high tension) into the<br />

tapped holes in the end face of<br />

the clutch. See illustration on the<br />

right.<br />

2. A press fit is required for MX<br />

Series clutches for indexing<br />

applications, but do not exceed<br />

0.025 mm when press fitting.<br />

3. Adjust the side of the key to fit<br />

the keyway tightly, but allow a<br />

clearance between the top of<br />

key and keyway.<br />

4. When mounting the clutch on a<br />

shaft, apply pressure to the<br />

clutch inner race end, but never<br />

to the outer race.<br />

5. Proper selection of the Cam<br />

Clutch provides accurate<br />

indexing performance. A braking<br />

device and a backstopping<br />

device may also be required for<br />

more accurate performance.<br />

6. The tolerance of the hub bore<br />

should be H6 or H7.<br />

Installation and Usage<br />

1. When mounting sprockets or gears to the outer<br />

race, use the outer race inner dimension (dimension<br />

E) to make a centering flange on the sprocket or<br />

gear. Then attach firmly with bolts of tensile strength<br />

10.9 or greater to the tapped holes in the outer<br />

race. Recommended tolerance between mounted<br />

gear and centering flange is f7.<br />

2. The recommended shaft tolerance is h6 or h7.<br />

3. Always use a parallel key, and do not use a tapered<br />

key. A parallel key meeting ISO R773 (DIN 6885.1)<br />

is recommended. Make sure that there is no lateral<br />

play between the key and keyways. Install an end<br />

plate on the face of the inner race<br />

4. When inserting the shaft, apply pressure only to the<br />

face of the inner race only.<br />

5. See “Lubrication and Maintenance” on page 75.<br />

3. Before installation, verify that the direction of rotation<br />

of the inner race of the BS Cam Clutch (shown by the<br />

arrow on the inner race) is the same as the direction<br />

of rotation of the conveyor.<br />

4. Securely install the torque arm to the BS Cam Clutch<br />

using bolts of strength 10.9 or higher. Make sure that<br />

the contact between the surface of the torque arm<br />

and the side of the outer race is level and free of dust.<br />

5. Recommended shaft tolerance is h7 or h8.<br />

6. When inserting the BS Cam Clutch on the shaft,<br />

apply pressure only on the inner race. Do not tap the<br />

inner race directly with a hammer or exert any force<br />

upon the outer race, dust seal, or dust plate.<br />

7. Always use a parallel key for installation onto the<br />

shaft and then fix the BS Cam Clutch to the shaft with<br />

the end plate. Never use a tapered key.<br />

8. When installing models above BS160 (grease<br />

lubricated types), place one of the four oil plugs in<br />

the direct bottom location. This will allow for easy<br />

drainage of the grease for cleaning.<br />

9. While the shaft is rotating, the end of the torque arm<br />

will swing to some extent in the direction of rotation.<br />

Support the torque arm end only in the direction of<br />

rotation, but be sure to allow it a certain amount of<br />

free swing. If the torque arm end is fixed securely<br />

BS220 to BS450 BS30 to BS200<br />

Total clearance should<br />

(see installation diagram), the inside of the clutch<br />

be from 2 to 5 mm.<br />

becomes twisted, and this can result in damage to<br />

the components.<br />

10. For models BS30 to BS200, a single torque arm on<br />

one side is sufficient, but for models 220 to BS450,<br />

use two torque arms, one on each side. Install the<br />

torque arms evenly so the force is transmitted<br />

through the center of the clutch.<br />

11. Torque arms for the BS Cam Clutch are standardized.<br />

12. See “Lubrication and Maintenance” on page 75.<br />

Notes:1. BS Cam Clutch can be bored according to<br />

your specifications, but please specify the<br />

bore diameter with tolerance and keyway<br />

dimensions. If the tolerance and keyway are<br />

not specified, a tolerance of JIS H8 for the<br />

bore (JISB0401-1965) and keyway as per JIS<br />

(JISB1301-1959) Class II for parallel keys will<br />

be applied.<br />

2. To fix the torque arm, follow the installation<br />

instructions given on page 49.<br />

■ INSTALLATION PROCEDURE OF OIL RESERVOIR TYPE BS <strong>CAM</strong> <strong>CLUTCH</strong><br />

Pre-Installation<br />

1. The oil reservoir and the end plate are bolted to the<br />

BS Cam Clutch when packing to prevent dust from<br />

entering during transportation. Carefully detach them<br />

from the clutch.<br />

To prevent dust from entering the clutch during<br />

installation, we recommend that the BS Cam Clutch<br />

be put on clean paper when being handled.<br />

2a. For models BS160 and BS200R:<br />

Remove the dust cover from the clutch, and apply<br />

grease to the seal supporter to fill the space<br />

between the seal supporter and the dust cover.<br />

2b. For models BS220R through BS450R:<br />

Detach and separate the dust cover from the clutch<br />

after loosening the bolts. Apply grease to the seal<br />

supporter to fill the space between the seal<br />

supporter and the dust cover.<br />

3. Attach the dust cover to the clutch.<br />

4. Check that the direction of rotation of the conveyor<br />

shaft is the same as that of the free-wheeling side of<br />

the Cam Clutch inner race viewed from the oil<br />

reservoir side. The direction of the Cam Clutch freewheeling<br />

is shown by the arrow mark on the inner<br />

race end of the Cam Clutch.<br />

5. Attach the torque arm to the clutch using bolts. The<br />

torque arm for models BS250 through BS450 can be<br />

attached after mounting the clutch on the shaft, if<br />

there is enough open space around the conveyor<br />

shaft end. For more information on installing a torque<br />

arm, see “Installation and Usage” on page 44.<br />

Installation<br />

1. Set the V-ring on the shaft shoulder. Mount the<br />

clutch on the shaft. Apply pressure only on the<br />

inner race to slide the clutch to the shaft shoulder.<br />

DO NOT APPLY PRESSURE TO THE <strong>CLUTCH</strong><br />

OUTER RACE OR THE SEAL SUPPORTER. For<br />

securing the clutch, use only a parallel square key<br />

and ensure that there is clearance between the key<br />

ceiling and keyway. DO NOT USE A TAPERED<br />

KEY. Please see “Installation and Usage” on page<br />

44.<br />

3. Attach the end plate with the packing to the shaft<br />

using the bolts and apply sealing paste. ALWAYS<br />

USE THE SEAL WASHERS WITH THE BOLTS,<br />

otherwise oil leakage may occur.<br />

4. After cleaning the inside of the oil reservoir, apply<br />

the sealing paste on the connecting surface of the<br />

oil reservoir. For models BS160R and BS200R,<br />

attach the oil reservoir to the outer race end with<br />

the bolts, placing the oil level gauge at the correct<br />

position as shown. For models BS220R through<br />

BS450R, attach the oil reservoir to the seal<br />

supporter using the bolts, placing the oil level<br />

gauge at the correct position as shown.<br />

5. Push the V-ring to contact with the dust cover for<br />

maximum protection from dust.<br />

Explanation 1<br />

The Tsubaki Backstop Cam Clutch, a one-way clutch with the safest reverse rotation prevention qualities<br />

available, was manufactured mainly for installation on the low speed shaft of inclined conveyors or bucket<br />

elevators. The backstop cam clutch as well as all other Tsubaki Cam clutches is a one-way, sprag type clutch.<br />

Compared to other one-way clutches (ratchet or roller ramp clutch) similar in size, overheating during times when<br />

the motor is idling is significantly lower. This helps maintain superb lubrication qualities thereby improving the<br />

wear life of the clutch. Extended fatigue life is also obtainable due to the clutch’s large torque capacity.<br />

Both the European style BSEU series, as well as the BS series cam clutch which boasts thirty years of reputable<br />

performance since its introduction, can be used as reverse rotation prevention cam clutches for an array of<br />

conveyor sizes. Applicable shaft sizes range from ø20 ~ ø450 mm and torque range from 216 ~ 686,000 N·m.<br />

Installation and usage for BSEU series<br />

1. We recommend using a shaft tolerance of h7 or h8<br />

for Cam Clutch installation.<br />

2. ISO R773 (DIN6885.1) keyway is standard.<br />

3. Before installation, verify that the direction of rotation<br />

of the inner race of the Cam Clutch (shown by the<br />

arrow on the inner race) is the same as the direction<br />

of rotation of the conveyor.<br />

4. When inserting the Cam Clutch on the shaft, apply<br />

pressure only on the surface of the inner race with a<br />

soft hammer. Never strike the Cam Clutch with a<br />

steel hammer or apply unnecessary impact loads.<br />

5. Always use a parallel key for installation onto the<br />

shaft and then fix the Cam Clutch to the shaft with<br />

the end plate. Never use a tapered key. Allow for a<br />

clearance between the top of the clutch keyway<br />

and the top of the key for pressure ventilation. A<br />

pressure ventilation hole is provided on the keyway<br />

of the clutch’s inner race.<br />

6. Use the frame or a pin to eliminate outer race<br />

rotation.<br />

7. Set a 0.5 mm degree clearance between the torque<br />

arm and the frame (torque arm stopper) or the long<br />

slit in the torque arm and the pin. If the torque arm<br />

is rigidly mounted, it will apply a load to the Cam<br />

Clutch which may eventually damage it.<br />

8. The Cam Clutch is pre-packed with low temperature<br />

grease before shipment and is ready for installation<br />

and operation. No lubrication maintenance is<br />

required. The ambient operational temperature<br />

range is –40° to 50°C. However, the maximum<br />

temperature should be determined depending on<br />

the number of shaft revolutions. Further, if the<br />

number of shaft revolutions is low, a higher ambient<br />

operational temperature range is allowable. Consult<br />

with Tsubaki for more details.<br />

Explanation 2<br />

Other Possible Applications:<br />

BSEU Series Cam Clutches may also be used for low frequency indexing applications. A maximum indexing<br />

frequency of no more than 50 cycles/min. and a safety ratio of 2.5 times higher than the working torque are<br />

required. Be sure that the stress applied to the torque arm functions at a right angle in relation to the shaft<br />

direction. If the stress that is applied to the torque arm is set diagonally, the inner parts of the clutch will entangle<br />

causing damage and drastically reduce the operational life of the Cam Clutch.<br />

2) Tap the inner race lightly with a soft hammer moving<br />

around the race circumference so the Cam Clutch<br />

moves slowly and uniformly onto the end of the shaft.<br />

Make sure that the outer race does not become<br />

dislodged.<br />

3) Place an end plate over the inner race and use the<br />

mounting bolts to pull the Cam Clutch onto the shaft<br />

as shown in the diagram at right.<br />

4) Tighten the end plate securely.<br />

4. If you are installing the outer race first, check the<br />

precision of the fit. The tolerances for outer race<br />

mounting are shown in the tables at right. Verify that the<br />

correct tolerances can be obtained. Out of spec<br />

installation could damage the Cam Clutch.<br />

5. To lubricate the Cam Clutch, apply lubricant at the<br />

outer circumference of the inner race (see installation Parallel Tolerances<br />

Installation example 1:<br />

Installation and Usage<br />

1. We recommend using shaft tolerances of h6 or h7 for<br />

Cam Clutch installation.<br />

2. Use a ISO R773 (DIN 6885.1) parallel key. Make sure<br />

that the key does not move in the keyway. A loose key<br />

will damage the Cam Clutch.<br />

3. When installing the Cam Clutch over a shaft, please<br />

follow the procedure outlined below. Never hit the<br />

clutch with a steel hammer or apply unnecessary<br />

impact loads.<br />

1) Verify the Cam Clutch direction of rotation. The<br />

arrow on the inner race shows the free running (cam<br />

disengaged) direction. Make sure that the direction<br />

of cam engagement matches the intended<br />

application.<br />

2) Tap the inner race lightly with a soft hammer moving<br />

around the race circumference so the Cam Clutch<br />

moves slowly and uniformly onto the end of the<br />

shaft. Make sure that the outer race does not<br />

become dislodged.<br />

3) Place an end plate over the inner race and use the<br />

mounting bolts to pull the Cam Clutch onto the shaft<br />

as shown in the diagram at right.<br />

4) Tighten the end plate securely to make sure that the<br />

Cam Clutch cannot move on the shaft.<br />

4. If you using a torque arm, make sure that the bolts<br />

used to mount the torque arm have a tensile strength<br />

of 10.9 or greater, and tighten them securely.<br />

5. Set a 2mm clearance between the torque arm and the<br />

torque arm stopper. If the torque arm is rigidly<br />

mounted, it will be applying a load to the Cam Clutch<br />

which can eventually damage it.<br />

6. Install an appropriate coupling if there is a chance that<br />

the shaft will elongate from thermal expansion as<br />

encountered in some exhaust fan auxiliary drive<br />

system applications (see figure 4).<br />

7. If thrust loads are encountered, install a thrust bearing<br />

which will prevent those thrust loads from being<br />

transferred to the Cam Clutch.<br />

8. The Cam Clutch is pre-packed with grease before<br />

shipment and is ready for installation and operation.<br />

General Information for Installation and Usage<br />

11. BREU series is a modular type Cam Clutch which is delivered as a BREU series Basic type or BREU-K series<br />

with option parts (E1, E2, E5, E7 flanges, E3 Torque arm and E4 cover) which are required as separate parts.<br />

12. All models are pre-greased.<br />

The operational temperature range is –40°C to +40°C.<br />

Too much additional grease to both bearing inhibits the basic Cam Clutch function. Refer to page 63 for the<br />

maintenance.<br />

13. We recommend a Shaft tolerance of h7, and DIN6885.1 keyway is standard.<br />

14. We recommend tolerance of B and E H7 or H8 for sprockets, gears and other fitted parts.<br />

15. Clean the surface of both end of the outer race and the contact surfaces of the flanges, torque arm and<br />

cover.<br />

16. Verify the direction of rotation and attach the flanges, torque arm or cover.<br />

17. When installing sprocket, gear, and other equipment to the clutch, fit them on the surface of the flange by<br />

using hexagon socket cap screws.<br />

18. By installing each option part on the opposite side, the direction of rotation can be changed.<br />

19. Fix the grease nipple and set screw to the option parts.<br />

10. When mounting the clutch onto the shaft, apply pressure to the inner race but never to the outer race. Tap the<br />

inner race lightly with a soft hammer moving around the race circumference so the Cam Clutch moves slowly<br />

and uniformly onto the end of the shaft.<br />

11. Do not use grease that contains EP additives.<br />

12. Model No. BREU K<br />

No Mark : No keyway on the outer race.<br />

Installation and Usage<br />

1. By installing both parts on the opposite side, the direction of<br />

rotation can be changed.<br />

2. When mounting the clutch onto the shaft, apply pressure to the<br />

inner race but never to the outer race. Tap the inner race<br />

lightly with a soft hammer moving around the race<br />

circumference so the Cam Clutch moves slowly and uniformly<br />

onto the end of the shaft.<br />

3. All models are pre-greased.<br />

The ambient temperature range is –40°C to +40°C.<br />

Too much additional grease to both bearing inhibits the basic<br />

Cam Clutch function. Refer to page 65 for the maintenance.<br />

4. Refer to page 56 for other general information and page 64 for<br />

Installation and Usage<br />

1. By installing E1 flange and E2 flange on the opposite side, the<br />

direction of rotation can be changed.<br />

2. When mounting the clutch onto the shaft, apply pressure to the<br />

inner race but never to the outer race. Tap the inner race<br />

lightly with a soft hammer moving around the race<br />

circumference so the Cam Clutch moves slowly and uniformly<br />

onto the end of the shaft.<br />

3. All models are pre-greased.<br />

The ambient temperature range is –40°C to +40°C.<br />

Installation and Usage<br />

1. By turning the Cam Clutch on the opposite side, the direction<br />

of rotation can be changed.<br />

2. Fix the grease nipple to the option parts.<br />

3. When mounting the clutch onto the shaft, apply pressure to the<br />

inner race but never to the outer race. Tap the inner race<br />

lightly with a soft hammer moving around the race<br />

circumference so the Cam Clutch moves slowly and uniformly<br />

onto the end of the shaft.<br />

4. All models are pre-greased.<br />

The ambient temperature range is –40°C to +40°C.<br />

Too much additional grease to both bearing inhibits the basic<br />

Cam Clutch function. Refer to page 63 for the maintenance.<br />

5. Refer to page 56 for other general information and page 64 for<br />

maintenance.<br />

Installation and Usage<br />

1. By installing the E2 flange and E7 flange on the opposite side,<br />

the direction of rotation can be changed.<br />

2. Fix the grease nipple to the option parts.<br />

3. When mounting the clutch onto the shaft, apply pressure to the<br />

lightly with a soft hammer moving around the race<br />

circumference so the Cam Clutch moves slowly and uniformly<br />

4. All models are pre-greased.<br />

Too much additional grease to both bearing inhibits the basic<br />

Cam Clutch function. Refer to page 63 for the maintenance.<br />

5. Too much overhang load to F7 flange also inhibits the basic<br />

Cam Clutch function. Add one more bearing to the fixed<br />

equipment on the correct center line if the overhang load is<br />

big.<br />

Installation and Usage<br />

1. BREU-(K) C series Cam Clutch couplings make use of BREU series Cam Clutch and CR type couplings<br />

without cover.<br />

2. Mount the clutch loosely on the high-speed shaft at first.<br />

3. Accurately align both sprockets by checking with a straight edge on the teeth of both sprockets.<br />

4. Check whether the clearance(S) between the two sprockets is correct, then wrap the chain around the<br />

sprockets.<br />

5. Specify right hand (RH) or left hand (LH) as inner race overrunning direction from the view of cam clutch side<br />

(*) when ordering. See the above drawing.<br />

6. The same lubrication as for Tsubaki roller chain is necessary for the coupling chain.<br />

7. Ensure that the chain is properly closed with a connecting link and that the closed of the spring clip is installed<br />

in the same direction as the rotation of the outer race.<br />

Lubrication<br />

BREU series Cam Clutches need periodic maintenance and lubrication to both bearing to provide maximum<br />

performance throughout their service life. Lack of prescribed maintenance and lubrication will shorten the<br />

Service life of Cam Clutch and may cause unnecessary mechanical damage.<br />

Maintenance<br />

BREU series Cam Clutches are pre-greased at the factory and should be re-greased every three months for both<br />

bearings after installation. Follow the procedure below.<br />

1. Remove the set screw at the flange, torque arm or cover.<br />

2. Inject equal amounts of grease into the bearing from the grease nipple. Refer to the grease volume table for<br />

the correct amount.<br />

3. Run the Cam Clutch disengaged for from 20 to 30 minutes with the set screw removed. Excess of grease in<br />

the clutch area will flow out of the tapped holes. Be careful to avoid over greasing. Too much grease in the<br />

clutch will cause it to run hot, interfere with the clutch action, and may lead to mechanical damage.<br />

4. Wipe off excess of grease and re-install the set screw.<br />

Installation and Usage<br />

1. MG Series Cam Clutch is used for<br />

high speed inner race overrunning<br />

applications. MI Series Cam Clutch<br />

is used for indexing applications.<br />

2. For attaching a pulley, a gear, or<br />

sprocket to the clutch, insert the<br />

clutch into the hub of the device,<br />

and screw the bolts (high tension)<br />

into the tapped holes on the clutch<br />

end. The tolerance bore of the hub<br />

should be H6 or H7 of JIS<br />

standard. See the installation<br />

illustration on page 66.<br />

3. Recommended shaft tolerances<br />

are as follows:<br />

Model<br />

M 300, M 400<br />

M 500, M 600<br />

M 700<br />

M 750, M 800<br />

4. The key should be in accordance<br />

with JIS B1301-1959. However, for<br />

M750 and above models, a key is<br />

attached.<br />

5. Use only a parallel key to secure<br />

the clutch. Never use a tapered<br />

key.<br />

6. If the clutch receives shock loads<br />

or is designed for use at full torque<br />

capacity, it is better to use a<br />

hardened key and shaft.<br />

7. Allow for a clearance between the<br />

top of the clutch keyway and the<br />

top of the key for pressure<br />

ventilation of the clutch in the case<br />

of MG Series. A pressure<br />

ventilation hole is provided on the<br />

keyway of the clutch inner race.<br />

9. Thrust load should be taken up by<br />

other devices, not by the Cam<br />

Clutch.<br />

10. When using MG Series at medium<br />

and high speeds, pay attention to<br />

heating. Longevity is shortened if<br />

the temperature of Cam Clutch<br />

outer race rises to over 70°C. In<br />

this case, use a different model or<br />

provide an oil bath or forced<br />

lubrication.<br />

11. Oil is not sealed in at the time of<br />

shipment. Supply an appropriate<br />

amount of oil before use.<br />

12. When placing an order for MG<br />

Series Cam Clutch model MG 750<br />

and above, please inform <strong>TSUBAKI</strong><br />

of the overrunning speed you use.<br />

Installation and Usage<br />

1. MR Series Cam Clutch is used<br />

for outer race overrun in highspeed<br />

applications.<br />

2. For attaching a pulley, a gear, or<br />

a sprocket to the clutch, insert<br />

the clutch into the hub of the<br />

said device, and screw the bolts<br />

(high tension) into the tapped<br />

holes on the clutch. The<br />

tolerance of the bore hub should<br />

be H6 or H7 of ISO R773. See<br />

the illustration on this page.<br />

3. Recommended shaft tolerances<br />

are as follows:<br />

Model<br />

MR 750, MR 800<br />

MR 900, MR 1000<br />

Tolerance<br />

+0 to –0.035<br />

+0 to –0.040<br />

4. When mounting the clutch on a<br />

shaft, apply pressure to the<br />

clutch inner race, but never to<br />

the outer race.<br />

5. Allow for a clearance between<br />

the top of the clutch keyway and<br />

the top of the key for pressure<br />

ventilation. A pressure ventilation<br />

hole is provided on the keyway<br />

of the clutch inner race.<br />

6. When the clutch receives a<br />

shock load or is designed for<br />

use at full torque capacity, it is<br />

better to use it on an<br />

unannealed or hardened shaft.<br />

7. Thrust load should be taken up<br />

by other devices, not by the<br />

Cam Clutch.<br />

8. MR Series Cam Clutch includes<br />

special keys (hardened) which<br />

have a special height<br />

dimension. The depth of the key<br />

groove for the shaft should<br />

comply with ISO R773.<br />

9. Forced lubrication is<br />

recommended for continuous<br />

operation. Consult <strong>TSUBAKI</strong><br />

regarding the method.<br />

10. Oil is not sealed in at the time of<br />

shipment. Supply an appropriate<br />

amount of oil before use.<br />

Typical installation drawing<br />

MG, MI, MR Series<br />

Lift-off (Outer race rotation type)<br />

MR Series Cam Clutch is structured<br />

so that the cam rotates together with<br />

the outer race when the outer race<br />

overruns. As shown in the figure, the<br />

spring force (Fs) works to make the<br />

cam come in contact with the inner<br />

and outer races with fixed pressure.<br />

Conversely, the eccentric force (Fc),<br />

which works on the cam when<br />

overrunning, applies a moment in the<br />

direction where the cam does not<br />

contact the inner and outer races.<br />

Accordingly, when the overrunning<br />

speed is increased, the eccentric<br />

force (Fc) increases and the<br />

movement is augmented over the<br />

movement caused by the spring<br />

force. Next, the cam lifts off from the<br />

inner race and loses contact with it.<br />

This phenomenon is called “lift-off.”<br />

In this state, there is no friction on the<br />

cam and it continues overrunning as<br />

long as the bearing lasts.<br />

Installation and Usage<br />

1. MG-R Series Cam Clutch<br />

consists of MG Series Cam<br />

Clutch and oil reservoir. See<br />

“Installation and Usage” on<br />

page 66 for MG series clutch.<br />

2. These clutches are used for<br />

backstop applications.<br />

3. Specify right hand (RH) or left<br />

hand (LH) drive of inner race<br />

viewed from the end marked<br />

with the arrow.<br />

4. Prevent oil leakage from the<br />

shaft end by using an end plate<br />

with packing and sealed<br />

Reference for Cam Clutch Box Sizes<br />

Installation and Usage<br />

1. Pre-Installation:<br />

a. Check that the unit has not been damaged<br />

during shipment.<br />

b. Verify the specified rotational direction of every<br />

shaft.<br />

c. Do not apply impact shocks to the shaft when<br />

installing couplings.<br />

2. Installation:<br />

In order to prevent vibrations which can result from<br />

misalignment, make sure that the foundation where<br />

the Cam Clutch Box will be mounted is completely<br />

flat and rigid. Alignment tolerances of coupled<br />

shafts should be within 0.03 mm T.I.R. (Total<br />

Indication Reading). Recheck this specification after<br />

the installation is complete.<br />

3. Lubrication:<br />

Fill the Cam Clutch Box with the recommended<br />

lubricant up to the mark shown by the oil level<br />

gauge.<br />

4. Maintenance:<br />

Change the oil after the initial test run before putting<br />

the Cam Clutch Box into service, and change the oil<br />

every six months thereafter. Shut down the system<br />

before changing the oil. Procedure is 1) Drain the<br />

oil, 2) use flushing oil to clean the Cam Clutch Box,<br />

and 3) fill with fresh oil.<br />

5. Note for OB-SF Series.<br />

a. If you need to cool the OB-SF Series, run cold<br />

water (less then 35°C) through the cooling fin<br />

tubes at a rate of 10 liters per minute.<br />

b. To make inspection easier, the OB-SF series is<br />

equipped with a drag brake which prevents the<br />

system from turning the shaft by drag torque .<br />

Refer to operating manual for brake operating<br />

procedure.<br />

6. Please refer to the installation manual for the<br />

specific unit for more detailed information.<br />

a) Calculate the static torque reverse motion from the maximum<br />

load expected and multiply it by the service factor.<br />

b) Select the clutch by:<br />

a) design torque requirement<br />

b) max. overrunning speed<br />

c) bore and installation method<br />

Notes:<br />

1. The BS series is designed especially for mounting on the<br />

main drive shaft of conveyors, where the rotational speed<br />

is rather low, while the MG-R series is designed for highspeed<br />

backstop applications.<br />

2. Do not exceed the maximum torque of the clutch. Also,<br />

please consult <strong>TSUBAKI</strong> for special applications.<br />

For Belt Conveyors<br />

Selection Procedure:<br />

(1) Calculate the power to move an empty belt and idlers: (P1)<br />

r + r0<br />

P1 = 0.06 × f × W × V × (kW)<br />

367<br />

(2) Calculate the power to move a loaded belt horizontally: (P2)<br />

r + r0<br />

P2 = f × Qt × (kW)<br />

367<br />

(3) Calculate the power to move the load vertically: (P3)<br />

h × Qt<br />

P3 = (kW)<br />

367<br />

(4) Calculate the back stop power: (Pr)<br />

Pr = P3 – 0.7(P1 + P2) (kW)<br />

(5) Calculate the back stop torque: (T)<br />

9550 × Pr<br />

T =<br />

× SF (N·m)<br />

Use the values from the table below.<br />

SF<br />

Service condition<br />

1.5 Several times a day<br />

2.0 More than several times a day<br />

Note:<br />

For the conveyor types other than those in the above<br />

examples, calculate the backstop torque accordingly.<br />

Always allow for the maximum possible load in your<br />

calculations, since backstopping often occurs when the<br />

conveyor is loaded above its normal loading capacity.<br />

Motor Stall Torque Method<br />

Another method commonly used to select the proper<br />

backstop clutch size for conveyors is to use the motor name<br />

plate ratings plus the motor’s ability to produce excess<br />

torque. Depending on the motor size, it may develop over<br />

300% of rated torque. After stalling an overloaded conveyor<br />

can overload the backstop. For proper selection of the<br />

backstop, all facets of the mechanical system should be<br />

considered to ensure that the backstop is not the weakest<br />

link in the conveyor drive. If the motor breakdown torque is<br />

not known, refer to the motor manufacturer.<br />

Selection is based on the following formula:<br />

Motor name plate kW × 9550 S<br />

Motor stall torque T = × ≤ Tmax<br />

Shaft speed N (r/min) 100<br />

S = Stall torque percentage<br />

Tmax = Cam Clutch maximum torque at the 500,000 times<br />

point of the fatigue capacity graph (N·m)<br />

Tmax = Catalogue rated torque x 1.8<br />

or<br />

Motor name plate kW × 9550<br />

Motor stall torque T =<br />

× SF ≤ catalogue max torque<br />

Shaft speed N (r/min)<br />

Depending on motor stall torque,<br />

apply the following service factors:<br />

Stall torque<br />

Up to 180%<br />

Up to 240%<br />

Up to 300%<br />

Select the Cam Clutch which satisfies the calculated torque T.<br />

1. Do not use any EP additives in the oil or grease as they will shorten the Cam Clutch’s service life.<br />

2. The above oils and greases are recommended for operating environments ranging from –5°C to +40°C.<br />

Contact <strong>TSUBAKI</strong> for operating temperatures outside of this range.<br />

3. Package type Cam Clutches are shipped pre-packed with grease.<br />

4. Special Cam Clutch oil (1 liter can) and grease (500g can) are available from <strong>TSUBAKI</strong>.<br />

■ MAINTENANCE FOR THE BR SERIES<br />

Open Type Cam Clutch<br />

1. Follow the guidelines listed below for oil lubrication.<br />

1) Make sure there are no oil leaks at installation<br />

surfaces.<br />

2) Use the correct amount of oil, and when needed,<br />

replenish oil to the specified level only. Avoid over<br />

lubrication as it will cause the Cam Clutch to run hot.<br />

3) Change oil at least once every six months<br />

according to the following procedure:<br />

(1) Dispose of old oil.<br />

(2) Spin the Cam Clutch for 10 minutes in<br />

detergent oil in a free running condition (no<br />

clutch engagement).<br />

(3) Remove the detergent oil, and fill with new oil to<br />

the specified level.<br />

2. Follow the guidelines below for grease lubrication.<br />

1) Before running the Cam Clutch, remove the grease<br />

port plug and inject grease into the cam cage. The<br />

amount shown in the Grease Volume Table on the<br />

right.<br />

2) Run the Cam Clutch disengaged for 30 minutes<br />

with the grease port open. Excess grease around<br />

the clutches will flow out of the tapped holes.<br />

3) Wipe off the excess grease, and re-install the<br />

grease port plug.<br />

4) The Cam Clutch should be re-greased every three<br />

months according to the procedure outlined in<br />

steps 1 through 3 above.<br />

Package Type Cam Clutch<br />

Package type Cam Clutches are shipped pre-greased at<br />

the factory and should be re-greased every three months<br />

after installation. Follow the procedure below.<br />

1. Remove the grease port plugs at the bearing and cam<br />

cage.<br />

2. Inject equal amounts of grease into the cam cage and<br />

bearing. Refer to the Grease Volume Table for the<br />

correct amount.<br />

3. Run the Cam Clutch disengaged for 30 minutes with<br />

the grease port plugs removed. Excess grease in the<br />

clutch area will flow out of the tapped holes. Be careful<br />

to avoid over greasing. Too much grease in the Cam<br />

Clutch will cause it to run hot, interfere with the clutch<br />

action, and may lead to mechanical damage.<br />

4. Wipe off excess grease and re-install the grease port<br />

plugs.<br />

■ LUBRICANT REPLENISHING METHOD FOR THE MG AND MR SERIES<br />

1. As a general rule, the level of the<br />

lubricant should be equal to the<br />

height of the center of the shaft for<br />

overrunning or back-stopping<br />

applications.<br />

2. On every series, on the outer race,<br />

there are two to four plugs.<br />

3. On models that have four plugs,<br />

place them so that one is at the top,<br />

one is at each side, and one is at the<br />

bottom. Then remove the plugs from<br />

the top and the sides and insert oil<br />

into the top hole until it begins to spill<br />

out from the side holes.<br />

4. On models that have three plug,<br />

place one plug at the bottom and<br />

have the other two near the top.<br />

Remove the two upper plugs and<br />

insert oil into either side. Check the<br />

level by slowly turning the clutch until<br />

one of the upper plugs reaches the<br />

height of the center of the shaft.<br />

5. On models that have only two plugs,<br />

place one plug at the top position,<br />

remove its plug, and then insert oil.<br />

Then rotate the clutch 90°C to check<br />

that the oil is filled up to the level of<br />

the center of the shaft.<br />

■ LUBRICANT REPLENISHING METHOD FOR THE MI, MI-S, PO, PS, AND MX SERIES<br />

1. The level of the lubricant should be<br />

near the top of the inside of the Cam<br />

Clutch.<br />

2. On the outside surface or on the side<br />

surface, there are oil plugs for oil<br />

filling and draining.<br />

3. On models with three or four plugs<br />

on the outside surface, slightly turn<br />

the clutch and insert oil into one hole<br />

until oil begins to overflow out from<br />

one of its neighboring holes.<br />

4. On models with two plugs, insert the<br />

tip of the oil feeder into the plug and<br />

fill completely with oil until it<br />

overflows.<br />

5. On models with plugs on the side<br />

surface, place the two plugs lined up<br />

next to each other at the top, remove<br />

their plugs, and insert oil into one of<br />

them until oil begins to spill out from<br />

the other one.<br />

■ LUBRICANT REPLENISHING METHOD FOR THE MG-R SERIES<br />

1. As a general rule, the level of the<br />

lubricant should be equal to the<br />

center of the shaft. Verify the level of<br />

the oil by the window-type oil level<br />

gauge built into the oil reserve tank.<br />

2. On the outer race there are three or<br />

four oil plugs. Make one of these<br />

plugs the drain plug by installing the<br />

clutch so that the plug is at the very<br />

bottom. Since you insert oil through<br />

the oil plug on the oil reserve tank,<br />

install the oil reserve tank so that the<br />

oil plug is at the very top.<br />

■ SPECIAL LUBRICATION METHODS<br />

In some situations the Cam Clutch<br />

might be installed deep within your<br />

equipment making routine maintenance<br />

very difficult, or even impossible. The<br />

diagram on the left shows one such<br />

example.<br />

In this example, a through hole is<br />

prepared through the shaft, and the oil<br />

is forced into the clutch through a rotor<br />

seal.<br />

■ LIFE OF BR SERIES <strong>CAM</strong> <strong>CLUTCH</strong><br />

The service life of previous <strong>TSUBAKI</strong> Cam Clutch was<br />

determined as the frictional service life during<br />

freerunning (clutch disengaged) and the fatigue service<br />

life of the engaged clutch. However, with the new BR<br />

Series, freerunning frictional service life is not a factor<br />

because there is no mechanical contact when the clutch<br />

is disengaged. As a result, service life is determined<br />

solely by the fatigue life of the engaged clutch.<br />

Free-running r/min.<br />

0<br />

Non-contact range<br />

Contact time<br />

Free-running time<br />

(a) Contact time<br />

Non-contact time<br />

(b) Contact time<br />

Friction in the clutch mechanism only occurs during a very short<br />

period of time denoted by “a” and “b”. “a” is the time during which the<br />

cam is engaged until the acceleration of inner race causes it to<br />

disengage. “b” is the time during which the cam engages when the<br />

inner race decelerates.<br />

Fatigue Service Life<br />

Compression stress is generated when the cam is engaged<br />

against the inner and outer races. While the points at which the<br />

engagement compression are applied are not specifically<br />

determined, they will generally remain constant. As a result,<br />

torque loads repeatedly applied to the clutch will eventually<br />

result in pitting of the contact surfaces. Refer to the fatigue<br />

service life graph to determine the service life of the Cam Clutch<br />

in relation to clutch engagement cycles and applied load.<br />

Note: In cases where the load applied to the Cam Clutch<br />

changes, or where vibrational loads are encountered,<br />

repeated torque loads can be applied during a single<br />

clutch engagement. The Variable Load Torque Graph<br />

shows the type of repetitive torque loads which can<br />

be applied to the Cam Clutch in these cases.<br />

Repeated torque loads during a single clutch<br />

engagement can have the effect of increasing the<br />

overall torque load, and this must also be considered<br />

when determining Cam Clutch service life.<br />

Fatigue Service Life Graph<br />

The Fatigue Service Life Graph at right pertains the BR<br />

series Cam Clutch. The horizontal axis denotes the clutch<br />

engagement cycles, and the vertical axis the applied<br />

torque percentage of the maximum rated load of the Cam<br />

Clutch. (100% refers to the maximum rated load). The<br />

service life of the Cam Clutch is determined by<br />

comparing the clutch engagement frequency to the load<br />

applied as a percentage of maximum load.<br />

Variable Load Torque Graph<br />

Fatigue Service Life Graph<br />

Example: Cam Clutch type....................BR40<br />

Maximum rated load..............................980 Nm<br />

Applied torque ......................................588 Nm<br />

Torque percentage ................................60%<br />

Clutch engagement cycles ..................approx. 1,600,000<br />

In the above example, if a repetitive torque load were<br />

applied 10 times for each clutch engagement, the fatigue<br />

service life would reduced to 160,000 cycles.<br />
